Hybrid Ceramics have been recently introduced where ceramics have been combined with composite resins to solve the brittleness property of ceramics as well as providing modulus of elasticity close to that of dentine. A newly launched hybrid restorative material claimed to be the strongest restorative material in terms of compressive and flexural strength. The purpose of this study was designed to compare the marginal integrity and facture resistance of 3-unit e.max and Crystal Ultra FDP after thermocycling. Conclusion: Crystal Ultra Fixed Dental Prosthesis presented statistically higher mean marginal integrity values after aging than the IPS e.max CAD group. Fracture resistance of IPS e.max CAD group displayed statistically significant higher mean value than the Crystal Ultra group
